Lake Gaston Weed Control
Council
History of Treatment and
Chemical Purchase Contracts
Contracts
For An Aquatic Plant Management Program
The first five
year contract with Aquatic Nuisance Plant Control was approved upon
revisions to include recommended clarifications by the Lake Gaston Weed
Control Council at a meeting April 3, 1996. A representative of N. C.
Dept. of Water Resources, along with input from representatives from the
LGWCC, negotiated the contract with ANPC. Costs were $49 per treated
surface acre with a $30,000 management fee. This contract expired
December 31, 2000.
On December
27, 2000 the Lake Gaston Weed Control Council Board approved having
representatives of the LGWCC meet with ANPC to discuss renewal of the
contract. This included extending the current contract for five
months. The contract was renewed in July for a second five year term
ending December 31, 2005. Costs were the same as the first contract.
On October 12,
2005 the LGWCC Board approved the Contract Committee attempting to
negotiate a one year contract with ANPC for 2006. On January 4th,
2006 the Contract Committee reported being unable to negotiate a one
year contract for 2006. The Committee then recommended proceeding with
solicitation of sealed bids for treatment year 2006. Board approval was
received. At the February 22, 2006 meeting the Contract Committee
reported sending out five proposals. Three bids were received. ANPC
was solicited, but did not bid. The Committee recommended continued
negotiation for a contract with Professional Lake Management. This was
approved by the Board. At the meeting of March 29, 2006 the negotiated
contract for the year 2006 was presented to, and approved by, the
Board. This contract will expire December 31, 2006, but contains an
option to renew. Costs were $52 per surface acre for liquid application
and $59 per surface acre for granular application with a $25,000 lake
management fee (administration and service).
Chemical
Purchasing
The LGWCC is
responsible for procurement of and payment for all chemicals used in
connection with these treatments. Each year the LGWCC sends out for
quotes to two to four suppliers. LGWCC normally accepts the low bid for
the chemicals used. Recent quotes for bids on chemicals have been the
same for the chemicals used. All of these chemicals are manufactured by
SePro and are agency priced.

Grass carp,
at 8 per/acre, were put in based on the Dominion Flyover estimated
acreage of 3,174 During this same year, 2003, ANPC and LGWCC were
investigating using satellite imagery to more accurately measure and
illustrate invasive vegetated acres (2,438). Both agreed this would
provide better results year to year and $20,000 was included and
approved for the 2004 budget year. We plan to continue to use this in
future years. Dominion no longer does a flyover.
The 471
acres increase, for 2004, in invasive vegetated acres was confirmed by
satellite and visual observations. Details are reviewed and shown in
ANPC’s 2004 Satellite Imagery/Ground Survey - Invasive Vegetation
Mapping - Final Report Other sources for this information were, John
Madsen’s Assessment Report for 2004, LGWCC approved budget for 2004 and
Dominion/ANPC private treatment documents
